George,

2) Should we use the Name Length to decide where the end of the Session Name is, rather than checking on whether the character is printable or not?

Thanks,
Jane

No.  But it would not be illegal to add a multiple of 4 nulls.  But
optimally you should only add 0-3 nulls.

Only to find the end of the string.  I.e. if the last char is
printable it should pass.
